What does the time axis show?

The Combined waveform and Active harmonics graphs use the same time window. The full graph width shows exactly two cycles of the fundamental frequency.

One fundamental period2.273 ms1 ÷ f

Full graph width4.545 ms2 ÷ f — two cycles

Each of 8 grid divisions0.568 ms1 ÷ (4 × f)

In the Active harmonics graph, overtone n shows 2×n cycles in the same window: the fundamental shows 2, the second harmonic 4, the third 6, and so on.

These graphs are a calculated mathematical illustration of the waveform. They are not a real-time oscilloscope recording or measurement.
